关于类的方法参数传递问题
类的方法
public   static   getcontrol()
{
  .......
  Control   control_lr   =   Page.FindControl( "txtbox ")
  .......
}
这个Page页面,也就是调用方法的页面能作为参数传递进来吗?如果能,该怎么做呢?谢谢



------解决方案--------------------------------------------------------
public static getcontrol()
{
HttpContext ctx = HttpContext.Current;
if ( ctx != null )
{
System.Web.UI.Page page = ctx.Handler as System.Web.UI.Page;


Control control_lr = page.FindControl( "txtbox ")
}
.......
}
